Y-Series
24-28V, 20A, DUAL REDUNDANCY MODULE
9. “REDUNDANCY OK” RELAY CONTACT
This feature reports the loss of redundancy by opening the relay contact (pin 23 and 24).
Contact is closed When no errors are detected
Contact is open When:
- one or both input voltages are below 22Vdc or above 30Vdc.
- the output current is higher than the adjusted value of the output current threshold setting.
- an internal defect of the redundancy module is detected (decoupling measures and several
internal test routines).
Input voltage errors less than 2s will be ignored.
Overcurrent errors (less than 150% of the adjusted value) less than 4s will be ignored.
Overcurrent errors (above 150% of the adjusted value) less than 30ms will be ignored.
Internal errors less than 10s will be ignored
Contact ratings max. 60Vdc 0.3A, 30Vdc 1A, 30Vac 0.5A resistive load
min. 1mA at 5Vdc minimum permissible load
Isolation voltage See dielectric strength table in section 16.
10. “LOAD SHARE OK” RELAY CONTACT
This feature monitors if the output voltages of the two power supplies connected to the input are sufficiently adjusted
for an even current distribution. The relay contact (pin 13 and 14) is closed, when load sharing occurs.
Contact is closed When the adjustment of the output voltages are sufficient
Contact is open When an even load share does not occur and readjustment of the output voltages is
recommended.
Details see chapter 11.
